Configurable downlink and uplink channels for improving transmission of data by switching duplex nominal frequency spacing according to conditions

A method comprising:

• receiving sector information sent by a base station on a downlink channel, wherein the sector information indicates multiple uplink channels and multiple downlink channels available for use with the base station that sent the sector information, and wherein the multiple available uplink channels and the multiple available downlink channels are in the same frequency band;
• ascertaining an uplink channel based on the received sector information;
• and
• using the uplink channel to communicate with the base station.

A method comprising:

• determining loading on each of multiple uplink channels available for use with a base station, wherein the multiple available uplink channels are in the same frequency band;
• sending on a downlink channel sector information that indicates the multiple uplink channels available for use with the base station and information for the loading on the multiple uplink channels available for use with the base station;
• and
• communicating with at least one terminal on an uplink channel selected from the multiple available uplink channels based at least in part on the loading on the multiple uplink channels.

A method comprising:

• determining loading on multiple auxiliary downlink channels available for use with a base station, wherein the multiple auxiliary downlink channels are in the same frequency band;
• sending, on a primary downlink channel, sector information that indicates the multiple auxiliary downlink channels available for use with the base station and information for the loading on the multiple auxiliary downlink channels available for use with the base station;
• and
• communicating with at least one terminal on a downlink channel selected from the primary downlink channel and the multiple auxiliary downlink channels based at least in part on the loading on the multiple downlink channels.
